There are a lot of books and websites that give quite detailed guides to both basic and special stitches with picture of every step for people who want to learn the stitches. The aim with this guide is to remind people who already know them in case the stitch is needed for one of my patterns, but it should be possible to learn stitches directly from the guide too.

Special stitches:
Picot: a picot is a series of chain stitches that are joined to form a loop by making a slip stitch (ss) to the first chain (ch). A picot can consist of anything from 3 chains and upwards, all formed into a loop by a ss to the first chain. To make a picot you chain the number of times indicated and make a ss to the first ch. E.g. with a ch7 picot you ch 7 and ss to the first ch to make a loop.
